A groin strain is a tear or rupture in one or more of the adductor muscles, resulting in pain in the inner thigh area. This injury is often caused by running, jumping or making a sudden change in direction. It is frequently observed among rugby and football (soccer) players. Typical signs of the injury are a popping or snapping feeling at the time of the rupture followed by pain and swelling in the groin area. A hip spica can be an effective approach to reducing the pain of the injury and immobilizing the injured structures in order to assure a full recovery. However, this course of treatment should always be undertaken under the supervision of a doctor or other heath care professional.
